How the Brain Creates Individuality
Contribution to Well-Being from Understanding Diversity

  Neuroscience research has been based on the assumption that everyone activates the same brain regions for the same event. This assumption means, for example, that everyone activates the same brain regions for the response of the visual cortex to white vertical lines.
  We store various information and use it to make cognitions, judgments, etc. This Memory needs to be understood as a biological memory that is both linguistic and contains temporal information related to changes in the environment. For example, Memory includes genetically inborn determined physical characteristics and sensory sensitivities. On the other hand, some are related to environmental changes, such as lifestyle, eating habits, aging, and internal environment. Memory also includes epigenetic modifications, i.e., acquired mechanisms that adapt and control gene expression to the environment without changes in nucleotide sequences. In other words, MEMORY consists of all past experiences. It may be easier to understand that it is like the annual rings of a tree. Identical twins are genetically similar, but since they never experience the same environment twice, there are individual differences in this Memory. Memory for cognition and judgment is the principle that creates human diversity.
  Our laboratory focuses on how the brain forms identity using brain imaging, cognitive neuroscience, and social psychology. The formation of individuality is the principle of making human diversity. By understanding individuality scientifically, we aim to realize a science that can contribute to each individual's diverse well-being.
